Blue Jays' Gurriel Jr. out vs. Red Sox with hamstring tightness

Toronto Blue Jays outfielder Lourdes Gurriel Jr. will miss Tuesday's game against the Boston Red Sox due to hamstring tightness, TSN's Scott Mitchell reports.

Lourdes Gurriel Jr.‘s hammy tightened up on him last night so he’s getting the night off.#BlueJays will reevaluate him tomorrow.

Gurriel Jr.'s hamstring tightened up during Monday's 6-2 win over the Red Sox.

The 28-year-old will re-evaluated on Wednesday.

In 17 games this season, Gurriel Jr. is batting .297 with two home runs and 10 runs batted in. 

Mitchell also reports that starting pitcher Hyun Jin Ryu, who has been dealing with forearm inflammation, threw a bullpen session Tuesday.

Hyun Jin Ryu (forearm inflammation) is throwing a bullpen as we speak. How he feels coming out of it will determine next steps but doesn’t sound like the lefty will be out too much longer.#BlueJays

Ryu's timeline remains uncertain, but he appears to be nearing a return to the mound. 

The 35-year-old lefty is 0-0 in two starts with a 13.50 ERA  over 7.1 innings so far this season.
