VIDEO: Jon Singleton homers in major league debut


Astros first base prospect Jon Singleton was promoted to the majors on Tuesday after agreeing to a five-year contract worth just $10 million guaranteed and homered in his fourth major league at-bat:

Singleton had a .941 OPS with 14 home runs and 43 RBI in 54 games at Triple-A Oklahoma City before his promotion to Houston. The 22-year-old could be a monster — a monster without much earning power.

Free agent right-hander Henderson Alvarez signed a deal with the Tigres de Quintana Roo of the Mexican Baseball League earlier this week, FanRag Sports’ Jon Heyman reported Friday. The righty wasn’t necessarily too fringey a player to hack it in the big leagues, but there were no MLB takers in attendance during his showcase in Venezuela last month and he clearly felt it best to try his luck elsewhere.

The 27-year-old’s last major league gig came with the Phillies, for whom he delivered a 4.30 ERA, 6.8 BB/9 and 3.7 SO/9 over 14 2/3 innings in 2017. While he’s not too far removed from his first and only All-Star bid in 2014, he was besieged by shoulder issues in 2015 and 2016 and underwent season-ending surgeries as a result.

That added injury risk, coupled with the fact that he hasn’t pitched more than 22 innings in a single season since 2014, may have been too much for major league teams to take on this spring. Assuming he steers clear of further injuries, however, a return to the majors may not be entirely out of the question in years to come.
