ATLANTA – A few weeks ago at PNC Park, Jim Jarvis was freshly called back up to the majors for his second stint with the Braves and was asked about the opportunity to prove he could fill the much-needed void at shortstop.“The main goal would just be to try to help the team win,” Jarvis said on July 7. “Everyone up here is extremely talented. This team’s full of superstars, so I’m just trying to do my part.”Jarvis has done more than just his part — he’s given life to the position on both sides of the ball, and it’s clear the Braves have full trust in him to be the primary shortstop while Ha-Seong Kim has been absent with right middle finger inflammation.Since being recalled on July 2, Jarvis is hitting .319, smacked his first major-league homer in Pittsburgh and has driven in seven runs. Heading into Thursday’s 6-5 win over the Padres, Jarvis’ .871 OPS ranks third on the Braves (minimum 25 PA) behind Drake Baldwin (1.014) and Matt Olson (.948).Jarvis’ overall .308 batting average leads the National League among 65 other rookies with at least 50 plate appearances, and ranks third in MLB behind Joshua Kuroda-Grauer (.417) and Wade Meckler (.311). Jarvis is also one of nine rookies this season to collect at least 16 hits through his first 16 career games.“It feels like these days are just flying by,” Jarvis said after Wednesday’s 7-6 win against the Padres, where he delivered a go-ahead double. “I’m trying to enjoy it as much as I can, but it’s like you get to the field and it’s just all a blur, and then the game’s over. Go home and do it again.”Fans have given him the nickname “Jimmy Baseball” for his impact on the field and the way he plays the game. Jarvis runs the bases aggressively. He plays premium defense and has saved the Braves from giving up a few runs.Braves manager Walt Weiss admitted that he didn’t know much about Jarvis outside of his defense, but just like the rest of Braves country, the Alabama product has shown he can hold his own.“He understands how to take an at-bat,” Weiss said. “There’s not a lot of chase. He forces guys into the zone. He’ll draw the walk. He’ll take an at-bat according to what the scoreboard’s telling him. There’s some feel for the game there.“I think if you’re going to play in the middle of the field, especially at shortstop, you have to have a high baseball IQ.”
