Debut Details
September 1, in an 11-6 win over the Giants. The starting pitcher, he did not get a decision, allowing five runs, all earned, on eight hits over four innings, walking one (intentionally) while striking out six. Of 77 pitches thrown, 41 were for strikes. In the first, Denard Span struck out swinging, Kelby Tomlinson flew out to right and Joe Panik struck out swinging. In the second, Buster Posey led off with a single to left and scored on Brandon Crawford's two-run home run to right-center field. Hunter Pence then singled to left before Jarrett Parker flew out to left for the first out of the inning. Ryder Jones then singled to right to put runners at the corners. After Johnny Cueto struck out on a foul bunt attempt, Span's RBI single to center scored Pence before Tomlinson grounded out to shortstop to end the inning. In the third, Panik grounded out to first before Posey got things started with an infield single to second. Crawford then doubled to right before Pence's triple to center scored Posey and Crawford. After intentionally walking Parker to set up a force, Flaherty struck out Jones on a foul tip and struck out Cueto looking to end the threat. In the fourth, he retired the side in order with Span grounding out to the mound, Tomlinson striking out swinging and Panik grounding out to second before right-handed reliever John Gant took the mound in relief to start the fifth inning.

Player Notes
While Flaherty did not technically need to replace anyone on the Cards' roster when he was brought up, since it was the day MLB rosters expanded to 40, he takes the place of just-traded veteran RHP Mike Leake in the rotation. Just 21 at the time of his debut, he opted to sign out of exclusive Los Angeles prep school Harvard-Westlake , which boasts quite a nice baseball program, as evidenced by the fact that he was teammates with such up-and-comers as Max Fried (LHP, Braves) and Lucas Giolito R(HP, White Sox). In fact, with those two on the staff, Flaherty saw a lot of time at third base. A polished pitcher despite the recent full-time conversion to the mound after he signed, he has a fastball in the low 90s, a plus changeup as well as a curve and a slider. He combined this season to post a 1.42 ERA in 63 1/3 innings at Springfield, his Double-A debut, and barely missed a beat when promoted to Memphis, where he had a 2.74 ERA in 85 1/3 innings. He's allowed just a .239 combined average against since making his pro debut in 2014 in the Gulf Coast League (Complex), jumping up to Peoria (Class A) in 2015 where he was 9-3 with a 2.84 ERA in 18 starts over 95 innings, fanning 97. He was 5-9 with a 3.56 ERA in 24 games at Palm Beach (High A) in 2016, striking out 126 and walking 45 in 134 innings.
