New York Mets right-handed ace Matt Harvey has a partially torn ulnar collateral ligament in his pitching elbow.
Mets general manager Sandy Alderson said Monday that Harvey would go on the disabled list and is out for the season. It is not clear if he will need Tommy John surgery. If he does, he would miss the entire 2014 season.
Harvey, 24, complained about fatigue and discomfort after his Saturday start against the Detroit Tigers, in which he threw 102 pitches.
An MRI taken Monday revealed the tear. Harvey will have another test in the next two weeks after the swelling is reduced.
Harvey, who started this year's All-Star Game in New York, is 9-5 with a 2.27 ERA and is fourth in the league with 191 strikeouts.
--Forbes Magazine projects this year's Houston Astros to be the most profitable major league team ever.
The Astros, on pace to lose 108 games, have the lowest payroll in the majors. They are projected to make $99 million in operating income. That figure takes into account total revenues minus operating expenses.
ESPN lists the Astros' payroll at just over $21 million.
The club's profit is almost as much as the six previous World Series championship teams combined.
--The New York Yankees activated shortstop Derek Jeter from the disabled list, and the Yankees captain was in the lineup Monday night against the Toronto Blue Jays.
Jeter, 39, missed the past three weeks with a strained right calf. He sat out the first 91 games of the season while recovering from a broken ankle suffered in the 2012 American League Championship Series. In his return on July 11, he injured his right quadriceps against Kansas City. He was sidelined two weeks before returning for a handful of games before going back on the DL.
The Yankees cleared a roster spot for Jeter by optioning reliever Preston Claiborne to Triple-A Scranton/Wilkes-Barre.
--Three minor league players were suspended by Major League Baseball for violations of the Minor League Drug Prevention and Treatment Program.
Los Angeles Angels outfielder Brandon Bayardi, who is with the Orem Owls of the Pioneer League; New York Mets pitcher Daniel Huchingson, who is with Double-A Binghamton; and Toronto Blue Jays catcher Sean Ochinko, who is on the Triple-A Buffalo roster, were suspended for 50 games.
