Zach Eflin

A couple weeks ago, MLBTR’s Darragh McDonald highlighted the players who could choose to return to the free agent market via opt-out clauses. We’ll now take a division by division look at those whose contracts contain club, mutual or vesting options. That kicks off tonight with the AL East.

Although it’s early in the season, a lot of these provisions are fairly easy to predict. The mutual options are almost certain to be declined by either the player or team (usually the latter). They’re accounting measures, essentially an unofficial deferral within the term of the contract itself. The player agrees to push back a percentage of the guaranteed money to the end of the deal in the form of an option buyout — which is paid after the end of the World Series rather than evenly distributed during the regular season as salary.

Baltimore Orioles

• RHP Zach Eflin: $25MM mutual option ($2MM buyout)

Eflin’s return to the Orioles was dashed by yet another injury: an elbow ligament that required Tommy John surgery. The O’s probably weren’t signing up for a $25MM salary even if he’d stayed healthy this year, but this is as obvious a buyout as these decisions get.

• LHP Dietrich Enns: $3.5MM club option ($125K buyout)

Enns pitched well for the O’s down the stretch after a deadline trade from Detroit. The 34-year-old southpaw worked to a 3.14 ERA while striking out 28% of batters faced across 28 2/3 innings. Although he’s nowhere close to six years of MLB service time, his contract contained a 2026 club option that presumably had a clause ensuring he’d become a free agent if the team declined. That’s fairly common for players like Enns who had spent the preceding couple seasons pitching in Asia.

The O’s restructured Enns’ contract to pay him a $2.5MM salary and guarantee a $125K buyout on a $3.5MM team option for the ’27 season. He has walked five batters over 4 1/3 innings to begin this season. Enns landed on the injured list a couple weeks ago with a foot infection. He began a rehab assignment in Triple-A on Saturday. This one is too early to judge.

• 1B Ryan Mountcastle: $7.5MM club option

Mountcastle agreed to tack on a $7.5MM option to avoid going to an arbitration hearing last offseason. Speculatively, that’s probably due to the CBA provision which doesn’t fully guarantee salaries determined at an arbitration hearing until Opening Day. Had Mountcastle not settled, the O’s might’ve released him for termination pay during Spring Training after making a splash on Pete Alonso earlier in the winter.

Although the O’s were surely happy to get the extra year of club control, it probably won’t be of much benefit. Mountcastle broke a bone in his left foot last week and will miss at least two months. It’s his second straight year with a significant injury. He lost a couple months to a hamstring strain in 2025. Mountcastle was already an odd roster fit who’d make more sense as a trade chip. Maybe he’ll return in the second half and hit well enough that the O’s feel the option price is too good to pass up, but it’s likelier this is getting declined.

Boston Red Sox

• LHP Aroldis Chapman: $13MM mutual option ($300K buyout); vests at $13MM at 40 innings pitched

Chapman’s option vests if he reaches 40 innings pitched this season and passes an end of year physical. He has surpassed 40 frames in three straight seasons. He’s at 7 2/3 innings thus far. It’d take at least one injured list stint — probably an absence of 6-8 weeks — for him to fall short of 40 innings.

In any case, the Sox would be happy to have him back at that price if he’s healthy. Chapman was probably the best reliever in MLB last season, firing 61 1/3 innings of 1.17 ERA ball with a 37% strikeout rate. The punchouts are down early this year in an exceedingly tiny sample, yet he has only allowed one run and is 4-4 in save opportunities. He remains at the top of his game at age 38.

• RHP Sonny Gray: $30MM mutual option ($10MM buyout)

Gray restructured his contract as a condition of the offseason trade that sent him from St. Louis to Boston. The deal initially came with a $35MM salary for this year and a $5MM option buyout. Gray agreed to move $4MM of salary back to the buyout while picking up an extra $1MM as a condition for waiving his no-trade clause. He’ll be a free agent.

• RHP Garrett Whitlock: $8.25MM club option ($1MM buyout)

Whitlock’s contract comes with an $8.25MM team option that includes $4MM in unspecified escalators. There’s also a $10.5MM club option for the ’28 season. Whitlock has been one of the best setup arms in MLB throughout his career. He rebounded from an injury-plagued ’24 season to fire 72 frames of 2.25 ERA ball with a 31% strikeout rate last year.

The righty’s command has been a little wobbly this year and his sinker velocity is down a couple ticks. Still, he’s only allowed two earned runs while striking out 11 through his first nine innings. No other Boston reliever is getting higher-leverage assignments on average. This is one of the likelier options to be exercised.

New York Yankees

• None.

Tampa Bay Rays

• 1B Yandy Díaz: $10MM club option; converts to $13MM option which automatically vests at 500 plate appearances

Tampa Bay preemptively locked in Díaz’s $12MM club option for the 2026 season during Spring Training ’25. In exchange, the first baseman gave the team a $10MM option for ’27 that would vest at $13MM as long as he stayed healthy enough to reach 500 plate appearances. Díaz is a little over 20% of the way there. Even if he suffers an injury that takes the vesting provision off the table, he’s been such a good hitter that Tampa Bay would probably be happy to exercise the $10MM option.

• RHP Nick Martinez: $20MM mutual option ($4MM buyout)

The mutual option in the Martinez contract was purely one of the aforementioned accounting mechanisms. The Rays aren’t paying him a $20MM salary even if he pitches to their expectations. He’ll be bought out.

• CF Cedric Mullins: $10MM mutual option ($500K buyout)

The same is very likely true for Mullins. A $10MM option price is rich for Tampa Bay unless the former All-Star outfielder has a resurgent season — in which case, he’d decline his end and look for a multi-year deal. The early returns aren’t encouraging, as Mullins is hitting .156 with two homers through his first 21 games. Over the past calendar year, he’s a .194/.257/.336 hitter.

• RHP Drew Rasmussen: $8MM club option ($500K buyout); option could escalate up to $20MM depending upon Rasmussen’s health and innings total

Before the 2025 season, the Rays signed Rasmussen to a two-year deal that bought out his final arbitration years. It included a complex club option for 2027 that was heavily dependent on his health. The option comes with an $8MM base value but includes up to $12MM in escalators based on starts and time spent on the injured list.

Rasmussen had only once topped 80 MLB innings at the time of his extension. He has undergone multiple elbow procedures and broke into the league as a reliever because of durability concerns. Rasmussen has stayed healthy over the past year-plus. He pitched a career-high 150 innings en route to a top 10 Cy Young placement in 2025. He’s out to a similarly excellent start to the ’26 campaign, allowing just four earned runs through his first 19 2/3 innings.

The option value will begin to climb before long. It’ll jump to $8.5MM once he reaches eight starts and includes additional escalators for every fourth start up through 28 appearances. If he makes 28+ starts, it’d jump to a minimum of $14MM. That’s just the beginning, as the number climbs if he avoids a long-term injured list stint. It’d get up to $20MM if he goes the entire season without an arm injury.

At $8MM, Rasmussen is an unmitigated bargain even for a low-payroll Rays club. The escalators will probably climb quickly enough that he’ll be a trade candidate. That could happen midseason if the team isn’t in the playoff hunt or early next offseason if they hold him at the deadline. If Rasmussen repeats last year’s production, he’s not going to be in any danger of being bought out — as closer Pete Fairbanks was when escalators pushed his option value from $7MM to $11MM.

Note: The Rays hold a $3.1MM club option on INF Taylor Walls. He’d remain eligible for arbitration if the team declines.

Toronto Blue Jays

• CF Myles Straw: $8MM club option ($1.75MM buyout); Guardians paying Toronto $1.75MM at season’s end as part of 2025 trade

The Blue Jays acquired Straw in a salary dump trade with the Guardians over the 2024-25 offseason. Toronto agreed to cover $11MM of the remaining two years and $14.75MM on Straw’s underwater contract. (He’d gone unclaimed on waivers that same offseason and was no longer on Cleveland’s 40-man roster.) In exchange, the Guards sent the Jays international bonus pool space. Toronto could then increase their offer to Roki Sasaki by an extra $2MM in a late, ultimately unsuccessful effort to sway the star NPB pitcher away from signing with the Dodgers.

Sasaki’s decision to join L.A. made this initially look like a complete bust for Toronto. To his credit, Straw has salvaged the move. He made the team in 2025 and did a nice job in a fourth outfield role, hitting .262/.313/.367 while playing his typically excellent outfield defense. He’s out to a good start this season as well and provides a high-floor depth option if Daulton Varsho misses any time.

Will that be enough to convince the Jays to keep Straw around? They certainly didn’t anticipate exercising an $8MM option at the time of the trade. That’s made clear enough by the teams’ agreement for the Guardians to send Toronto a $1.75MM payment — which matches the buyout value — at the end of the ’26 season. Cleveland is sending the money either way, though, so it’d amount to a $6.25MM call if the Jays want to bring Straw back.

That’s a little rich for a fourth outfielder, which is what Straw has been for the last few seasons. Varsho is an impending free agent and the Jays don’t have anyone waiting in the wings from the farm system. Straw’s play and the possibility of Varsho walking has made this a tougher call than even the Jays’ front office would have anticipated.
