The Seattle Mariners' Felix Hernandez became the 36th major-league pitcher with 2,500 career strikeouts, getting it in the second inning Saturday against the Boston Red Sox.

The 33-year-old right-hander fanned rookie Michael Chavis looking with a 92 mph fastball for the milestone.

Hernandez is the fourth active pitcher to reach the mark — behind the Yankees' CC Sabathia, Houston's Justin Verlander and Washington's Max Scherzer.

Astros' Altuve hurting

Houston Astros star Jose Altuve seems likely to end up on the 10-day injured list after straining his left hamstring Friday.

Astros manager AJ Hinch said Saturday he's "not optimistic" the 2017 AL MVP can avoid an IL stint.

Altuve was pulled during the first inning of a 3-0 win over the Texas Rangers with hamstring discomfort after beating out an infield single. He was sent for tests Saturday, and the team is still awaiting a complete diagnosis.

Rays' Glasnow goes on IL

The Tampa Bay Rays placed pitcher Tyler Glasnow on the 10-day injured list because of a mild right forearm strain that is expected to sideline him four to six weeks.

Glasnow left during the sixth inning of Friday night's 4-3 loss to the New York Yankees with tightness in his forearm. An MRI performed after the game revealed the extent of the injury.

The Rays said Saturday the right-hander will be shut down from throwing for seven to 10 days, then be re-evaluated. Once he's cleared to resume throwing, Glasnow will need to be built back up to start.

Edwin Jackson nears mark

Edwin Jackson was acquired by the Toronto Blue Jays from the Oakland Athletics for cash and would set a record by pitching for 14 major-league teams when he makes his Blue Jays debut.

A 35-year-old right-hander, Jackson would be appearing in his 17th big-league season. He signed a minor-league contract with Oakland last month and was 1-0 with a 6.75 ERA in three games, two at Triple-A and one at Class A. He is expected to report to the Blue Jays and start at San Francisco on Wednesday.

Jackson has gone 104-123 with a 4.60 ERA in 394 games. He made his big league debut with the Los Angeles Dodgers in 2003 and also pitched for Tampa Bay, Detroit, the Chicago White Sox, Arizona, St. Louis, Washington, the Chicago Cubs, Atlanta, San Diego, Miami, Baltimore and Oakland. He was 6-3 with a 3.33 ERA in 17 starts for the Athletics last season, matching Octavio Dotel's record of 13 teams.
