The Houston Astros selected outfielder Marty Costes in the 22nd round (672nd overall) of the 2018 MLB Draft Wednesday afternoon, making him the first Maryland player chosen in consecutive drafts since 2013-14. He was selected by the Astros in the 25th round last year.
As a draft-eligible sophomore, Costes was the 751st overall pick in 2017, but returned to Maryland for his junior campaign. He is the second current Terp off the board this year, after Nick Dunn was taken in the fifth round on Tuesday.
Costes is now just the sixth Terp since 2000 to be selected in back-to-back drafts. Most recently, former right-hander Jake Stinnett was drafted in the 29th round (869th overall) in 2013 and then again in the second round (45th overall) in 2014. His teammate, outfielder Charlie White, jumped from the 29th round to the 21st round in the same two-year stretch.
Costes was an infielder out of Arcbishop Curley (MD) when he arrived at Maryland in 2016, but there were no immediate vacancies for him to start at third base. With the team needing his bat in the lineup, he was asked to transition to left field. In doing so, he ended the season tied with among Maryland’s outfield core with the fewest errors (2) and the most assists (4).
The urgency to get Costes’ bat into the lineup as a freshman paid off, as he lead the team with nine home runs, 21 extra-base hits and a .479 slugging percentage. His nine homers also led all Big Ten freshmen, helping earn a spot on the Big Ten All-Freshman team and a Louisville Slugger Freshman All-American nomination.
Coming off a first season filled with accolades, Costes continued to emerge during his sophomore campaign. He raised his batting average from .263 to .322, which ranked third on the team. One of two players to start in all 61 games, he led the team in hits (77), home runs (13), RBIs (46) and walks (34). His .322/.429/.548 slash line highlighted his selection as a 2017 All-Big Ten first team recipient and an MLB draft pick.
After playing with Dunn for the Brewster Whitecaps in the Cape Cod Baseball League last summer, Costes struggled a bit in his return to College Park as a junior. He had career-lows in batting average, hits, doubles, home runs, RBI and slugging percentage. However, he swiped double-digit bases for the first time and walked just as often as he struck out. Costes also continued to develop as an outfielder, showing off his strong arm with nine assists.
Despite the drop in numbers, Costes was much more productive during the final month of the season and his potential still warranted a second MLB Draft selection in as many seasons. His 96 career walks are the seventh-most in program history and his 28 homers are tied for eighth.
