Robert Gsellman’s first start as a member of the Mets’ rotation this week lasted just two innings, as the right-hander is still getting stretched out after opening the year in the bullpen. But manager Luis Rojas expressed confidence this week that the righty can “have some stamina for us” and “give us that depth to start a game” as he builds up (link via MLB.com’s Anthony DiComo). The 27-year-old Gsellman said he “felt like a little kid again” as he prepped for his first start since 2017, and DiComo notes that a move back into the rotation has long been something for which Gsellman has hoped. Righty Seth Lugo, too, has expressed interest in getting back into a starter’s role, but the Mets are more reluctant to alter his role given the resounding success he’s enjoyed as a late-inning weapon in recent years. Lugo has a career 2.50 ERA out of the ’pen and has punched out 28.3 percent of the hitters he’s faced in a relief role. Those numbers dip to 4.06 and 19.2 percent, respectively, in a nearly equal sample of innings as a starter.
More on the Mets…
- Amed Rosario has struggled to begin the season while top prospect Andres Gimenez has thrived in his early looks at shortstop. However, Rojas told reporters yesterday that Rosario is still the team’s starting shortstop (link via Newsday’s David Lennon). Rosario was out of action due to what the Mets termed as a stomach illness, but Rojas acknowledged after the game that the team is also “looking to get him back on track” at the plate. Rosario is hitting .207/.207/.310 to Gimenez’s .286/.327/.388. Gimenez has also played sharp defense and is tied for the MLB lead with five steals, but for now, it seems as though he’ll continue to slot in around the diamond. That could mean a move back to second base once Rosario is well enough to return to the lineup, but a changing of the guard at shortstop still doesn’t sound imminent. Gimenez, 20, has been generally considered to be among MLB’s top 100 prospects for the past couple of seasons, although Rosario himself was regarded as an elite prospect prior to his own ascension to the Majors.
- Left-hander David Peterson exited yesterday’s outing after just 74 pitches and revealed that he’s dealing with some shoulder fatigue (link via Mike Puma of the New York Post). Peterson, the Mets’ first-round pick back in 2017, had held the Nationals to a run one hit and a pair of walks through five strong innings. He said after the game that he’s not concerned with his shoulder issue. The Mets can ill afford any further hits to their rotation, particularly a loss of Peterson, who has been a godsend in the absence of Noah Syndergaard and Marcus Stroman. Through his first four MLB starts this year, Peterson has a 2.91 ERA and 3.96 FIP with a 17-to-8 K/BB ratio and just two homers allowed in 21 2/3 innings.
