The Philadelphia Phillies are in search of some pitching help, and they have talked to the Detroit Tigers about possibly trading for left-handed starter Matthew Boyd and righty reliever Shane Greene, according to Jim Salisbury of NBC Sports Philadelphia.

However, the price may be high, as Salisbury notes that one baseball executive said the Tigers were looking for four players for Boyd, of which two should have star potential and other two should have a chance.

Boyd has made 20 starts this season, going 6-8 with a 4.13 ERA. However, he has pitched better than his ERA may indicate, as he has allowed just 112 hits while striking out 160 batters over 120 innings. Plus, he owns a solid 3.55 FIP and has the best strikeout-to-walk ratio in the league at 6.67.

The 28-year-old broke into the majors with the Toronto Blue Jays back in 2015 but was traded to the Tigers midway through that season in a deal that sent David Price to the Blue Jays.

Up until this year, Boyd had struggled to find his footing, as he owns a lifetime ERA of 4.87 and a career FIP of 4.54, which could make teams like the Phillies hesitant to give up the type of package Detroit seems to be asking for.

Meanwhile, Greene has been the Tigers' closer this season, making 36 appearances out of the bullpen and logging 22 saves. He has pitched to the tune of a 1.25 ERA while surrendering 20 hits and fanning 40 hitters across 36 frames of work, making his first All-Star appearance as a result.

The 30-year-old owns a career ERA of 4.55 through 389.2 major-league innings.
