The Mariners announced today that they have recalled right-hander from Triple-A Tacoma. In a corresponding move, left-hander has been designated for a signment. The clubs 40-man roster count drops to 39. Castillo, 29, was just claimed off waivers from the Mets earlier this month. Since that claim, he has given the Mariners three scorele s innings. This move is likely more a result of circumstances than his performance. The Mariners are seven games into a stretch of ten in a row. The bullpen has been leaned on heavily in recent days. Five different relievers pitched on Tuesday. Then on Wednesday, six relievers were used in a game which went to 13 innings. Three of those six pitchers to sed more C.J. Miles Jersey than an inning. Last night, the club had another long one, using six relievers in a 12-inning game. Every reliever in the bullpen pitched at least twice in that three-day span except for , who logged two innings on Wednesday. Castillo himself pitched in each of the last two games and has seemingly been nudged out to get a fresh arm into the bullpen. Its been that kind of year for Castillo, who has generally pitched well. But since hes out of options, he has been forced into DFA limbo numerous times. He started the year with the Diamondbacks on a minor league deal. He was added to the big league roster at the start of May. Le s than two weeks later, he was designated for a signment and traded to the Mets. The latter club designated him for a signment three times. The first two resulted in him clearing waivers and later getting added back to the roster, but the Ms claimed him on the third. Hes now back in DFA limbo yet again. Since the trade deadline has pa sed, hell be back on waivers in the coming days. Around all the transactions, he has to sed 24 2/3 innings with a 4.38 earned run average, 19.5% strikeout rate, 9.3% walk rate and 55.7% ground ball rate. He has also thrown 16 Triple-A innings this year with a 1.69 ERA, 35.9% strikeout rate, 9.4% walk rate and 50% grounder rate. At this time of year, he wouldnt be postseason eligible with any claiming club, though perhaps some team is in need of a fresh arm for the stretch run. As mentioned, Castillo just appeared in the past two games but will have a chance to rest for a few days while on waivers. He could also be retained for next year via arbitration if hes on a roster somewhere at the end of the season. Photo courtesy of Vincent Carchietta, Imagn Images John Konchar Jersey
