The Giants have moved right-hander Jordan Hicks into a bullpen role. Hicks’s spot in the starting rotation will go to right-hander Hayden Birdsong, who is now slated to start for San Francisco against the Royals on May 20. Susan Slusser of the San Francisco Chronicle first suggested that the club was discussing the possibility of taking Hicks out of the rotation this afternoon, and manager Bob Melvin later confirmed the change to reporters (including Slusser) and announced Birdsong as Tuesday’s starter prior to tonight’s game.
It was just last week that Melvin suggested that moving Hicks out of the rotation was not something the Giants had begun discussing. Just a few days later, however, Hicks suffered his worst start of the season against the Diamondbacks as he was torched for five runs across just two innings of work. In that time, he surrendered seven hits (including a home run) and one walk while recording just one strikeout. It seems that outing, which raised Hicks’s ERA to 6.55 on the season, was the final straw for the Giants and convinced them that it was time to explore other options to round out the rotation behind Logan Webb, Robbie Ray, Justin Verlander, and Landen Roupp.
It’s an unfortunate end to Hicks’s time in the rotation, particularly given the fact that peripheral numbers have generally looked favorably upon the right-hander’s work with the club this year. The righty’s 20.3% strikeout rate doesn’t exactly jump off the page, but he’s walked just 7.9% of his opponents and generated an incredible 57.4% ground ball rate. That’s the sixth-highest grounder rate among all qualified starters this year, and of the five names above him only Webb has allowed less hard contact than Hicks’s minuscule 27.7% clip. That elite contact management has been held back by a sky-high .362 BABIP and a shockingly low 56.7% strand rate. Those figures suggest some bad luck and poor sequencing may be the culprit of Hicks’s struggles, and those ideas are further backed up by his 3.48 FIP and 3.74 SIERA.
That 3.79 figure the 30th best SIERA in baseball among qualified starters this year, sandwiched between Clay Holmes and Freddy Peralta. While Hicks’s peripheral numbers may suggest strong underlying performance, however, it’s hard to make the argument that this move to the bullpen was premature. Hicks is the worst qualified starter in the league by ERA this year, and his struggles actually date back to last season when he posted an ugly 8.18 ERA with a 6.44 FIP across his final five starts of the year before moving to the bullpen in the second half and returning to form with a 1.17 ERA in August.
While it’s far from impossible to imagine Hicks getting another look in the rotation at some point given those aforementioned strong peripherals, a number of injuries may be required in order for that to come to pass. After all, the Giants have an excess of starting talent that’s forced them to use well-regarded youngsters like Birdsong and recent top prospect Kyle Harrison out of the bullpen to this point in the season. Birdsong, who posted a 4.75 ERA in 16 starts as a rookie last year, has done everything that could be expected to earn another crack at starting this year with a 2.31 ERA and a 24.8% strikeout rate in 23 1/3 innings of work as a multi-inning relief arm. The righty’s 9.9% walk rate is elevated, but his 3.68 SIERA to this point in the year is even better than that of Hicks. As for Harrison, the southpaw began the season in the minors and has only made three appearances so far this year at the big league level, though he’s struck out 31.3% of opponents with a 2.25 ERA in that limited work.
