Spencer Turnbull and Matt Hall will join the Tigers on Tuesday, per report

On Monday, left-fielder Christin Stewart is slated to make his starting debut in the Detroit Tigers outfield. The Tigers also recalled reliever Zac Reininger, and catcher Jarrod Saltalamacchia, moving pitcher Artie Lewicki to the 60-day disabled list to open a 40-man roster spot for the veteran catcher. Apart from Stewart, this isn’t a very scintillating group of additions, but it looks like more help is on the way from Toledo.

Per a report from Evan Woodbery of MLive, the Tigers will also add a pair of interesting pitching prospects on Tuesday. Spencer Turnbull, a hard-throwing sinker specialist, and left-handed reliever Matt Hall, are expected to join the Tigers pitching staff, and should provide some intrigue as they make their major league debuts.

The 25-year-old Turnbull, selected by Detroit with their second round pick in the 2014 draft, made three strong starts for the Triple-A Toledo Mud Hens since his promotion from Double-A Erie. Including a short rehab stint in Lakeland, Turnbull posted a 3.92 ERA, with 133 strikeouts and 46 walks in 119 ¹⁄₃ innings, mainly at the Double-A level.

Hall is also 25 years of age, and was selected in the sixth round of the 2015 draft. The lefty features perhaps the best curveball in the Tigers’ system, though his fastball and changeup are mediocre and probably foretell a future role as a reliever. Hall split his season between Erie and Toledo, amassing a 2.13 ERA, with 135 strikeouts and 35 walks across 114 ¹⁄₃ innings of work.

Turnbull is already on the Tigers’ 40-man roster, so no corresponding move will need to be made in order to add him for the final three weeks of the season. Hall however, isn’t yet on the 40-man, and space will have to be made for him. The Tigers have numerous options, from cutting Triple-A level pitchers like Ryan Carpenter or Johnny Barbato, to potentially adding shortstop Jose Iglesias to the 60-man disabled list, assuming his oblique strain is going to require a few more weeks to heal. They could also release a veteran like Saltalamacchia or even starter Francisco Liriano, as there is little point to having older players eating playing time that could go to the youth movement.
