Olson went 4-7 with a 4.56 ERA in 25 appearances and 21 starts with the Bisons this season, having allowed 115 hits, 11 home runs, and 51 walks in 108 2/3 innings.
Left-handed hitters have hit .270 against Olson and he’s allowed 19 earned runs and 34 hits in 33 1/3 innings against them this season.
To make room on the 40-man roster for Olson, the Mets moved RHP Dillon Gee to the 60-day disabled list.
Gee was diagnosed with a clot in the artery in his throwing shoulder after reporting numbness in his pitching hand in a start against the Cubs before the All-Star break. He had surgery last month to repair the artery.
To make room for Olson on the active roster, the Mets optioned RHP Elvin Ramirez to Triple-A Buffalo.
Ramirez has gone 0-1 with a 7.30 ERA in 11 games and two stints with the Mets this season.
The move to add Olson to the bullpen is interesting, as he been starting for the Bisons for the majority of the season. In addition, Olson's numbers against lefties this season are not exactly stellar. However, the Mets don't have many quality options to chose from and adding a reliever from outside the organization may not be any better than the internal options. At any rate, with Tim Byrdak out for the season it does give Terry Collins an additional option to help out Josh Edgin until the September call-ups.
As for Ramirez, his Minor League dominance this season never translated at the Major League level due to his lack of command with the strikezone. Perhaps the jump is too great for him at this point and I hope he continues to develop because I do see potential in his ability.
