It has become cliche at this point, but the Bucs do have a record of helping to turn around once-productive pitchers. And O’Flaherty certainly fits the general mold of past refurbishment projects.
The 31-year-old was at one time rather dominant for the Braves, running up a 1.99 ERA over nearly 250 frames from 2009 through 2013. He averaged a pedestrian 7.2 K/9 in that span, but limited the free pass (2.5 BB/9), got a ton of easy outs (58.3% groundball rate), and was plenty useful even against right-handed hitters.
Things weren’t so rosy last year, his first full campaign back from Tommy John surgery. He ended with an abysmal 8.10 ERA, which only got worse after a mid-season trade from the Athletics to the Mets. And the peripherals weren’t great either, as O’Flaherty ended with 6.3 K/9 against 5.4 BB/9. He was able to generate grounders right at his career rate, and there are indications he suffered some bad luck (.388 BABIP, 57.6% strand rate), but clearly he has some work to do to get back on track in the coming spring.
