The Astros, Marlins, Rangers, Cubs, Twins, Giants, Brewers, Phillies and Mariners were on hand to watch the right-hander throw between 50 and 60 pitches for about 25 minutes. They are among the teams interested in signing Loux, who was drafted by Arizona before reportedly failing a physical.
"Things went about the same, similar velocity on the fastball and breaking pitches," Loux said in an e-mail to MLB.com. "[I] found myself breaking my hands later than I should so control wasn't quite as good as normal, but overall a decent bullpen [session]."
Astros area scout Rusty Pendergrass and Midwest supervisor Ralph Bratton were on hand, representing the Astros, according to KRIV-TV in Houston.
Loux was drafted No. 6 overall and reportedly failed a physical because of arm problems. Major League Baseball declared Loux a free agent and available to sign with any club beginning Sept. 1, awarding Arizona compensatory Draft picks. The Astros had interest in the Houston-area product before he was picked by Arizona.
Loux, who went 11-2 with a 2.83 ERA in 16 starts last season as a junior at Texas A&M, last week threw for about 25 minutes at his college, where he's finishing up his degree.
