Kelvin Marte

The Pirates have designated both lefty Kelvin Marte and righty Curtis Partch, the team announced. Their 40-man spots were needed to accommodate the organization’s latest wave of call-ups, which includes Tyler Glasnow, Pedro Florimon, Drew Hutchison, and Trevor Williams.

The 28-year-old Marte made his major league debut this year, throwing three and one-third scoreless innings but allowing two walks and five hits in that span while recording only a lone strikeout. He has converted to a relief role at Triple-A after previously working mostly as a starter, and carries a 3.67 ERA with 7.0 K/9 and 2.6 BB/9 over 73 2/3 frames there.

Partch, 29, was bombed in his two MLB appearances this year. But he was rather effective in his own stint at Indianapolis, compiling a 2.24 ERA in 60 1/3 frames. Partch notched sixty strikeouts in that span, though he also racked up thirty free passes.

The group of call-ups certainly holds some interest. Glasnow is the team’s highest-rated prospect, and he’ll return after making his debut earlier in the year. Trevor Williams has impressed at Triple-A despite lacking gaudy strikeout numbers. Florimon always seems to play a role somewhere in September, given his versatile glove.

And then there’s Hutchison, who was picked up in the somewhat controversial trade that sent Francisco Liriano (plus his contract) and two prospects to the Blue Jays at the trade deadline. The 26-year-old, who will be arbitration-eligible again next year, has worked to a 4.50 ERA in his 36 frames with Indy, with peripherals (7.0 K/9 against 3.8 BB/9) that fall shy of his work earlier this year at Buffalo.
