When players with significant Major League experience settle for minor league contracts, it's commonplace for these deals to contain opt-out clauses. If the player hasn't been added to the 25-man roster by a certain point, he can exercise the clause and seek employment with another organization. Such clauses aren't always made publicly available, but here's a list of some of the pitchers who have known opt-out dates that are nearing…
- Chien-Ming Wang, Yankees: Wang can opt out of his contract on May 31. In five starts spanning 31 2/3 innings at Triple-A thus far, the 33-year-old has a 2.84 ERA, 4.3 K/9 and 1.1 BB/9. The Yankees have said they don't feel Wang's minor league success will translate to the Majors just yet, as they want him to rely more on his breaking pitches than just his sinker.
- Tim Stauffer, Padres: Stauffer can opt out of his deal "around June 1," according to Bill Center of the San Diego Union-Tribune. He appeared in just one game for San Diego before needing season-ending surgery but posted a 3.24 ERA in 341 1/3 innings for the Friars from 2009-11. So far in Triple-A, the 30-year-old has a 3.16 ERA, 8.0 K/9 and 3.2 BB/9 in 42 2/3 innings.
- Sean O'Sullivan, Padres: Currently Stauffer's rotation-mate, O'Sullivan has the same opt-out clause in his contract (near June 1) despite being just 25 years of age. O'Sullivan has a 4.19 ERA, 8.2 K/9 and 2.7 BB/9 in 43 innings for Triple-A Tucson. He's had a rough time in the Majors, however, as evidenced by his 6.13 ERA in 193 2/3 big league innings.
- Jeremy Bonderman, Mariners: Bonderman's opt-out date is June 1, tweets ESPN's Buster Olney. Still just 30 years of age, Bonderman has been solid for Triple-A Tacoma. He's pitched to a 3.70 ERA, 5.4 K/9 and 2.4 BB/9 in eight starts spanning 48 2/3 innings. Olney feels Bonderman will opt out if he's not called up in the next couple of weeks, and I'm inclined to agree.
- Jair Jurrjens, Orioles: Jurrjens has an opt-out date of June 15. After a drastic fall from grace in the Braves organization, the 27-year-old has looked sharp at Triple-A Norfolk in 2013. He's compiled a 2.62 ERA, 5.8 K/9 and 3.0 BB/9 in seven starts spanning 44 2/3 innings.
All of the pitchers listed here have pitched well enough that they could make a case for helping a Major League team with a struggling rotation. It seems likely that by mid-June, each could force his way onto a Major League roster, even if it's with a new organization.
