PHILADELPHIA — When Braves manager Walt Weiss puts Drake Baldwin and Matt Olson back to back in the second and third spots of his lineup, he knows there is a good chance these two left-handed hitters will be challenged at some point by at least one lefty reliever.

Weiss could put Austin Riley in the middle of these two. But because he feels good about Baldwin and Olson against left-handed pitching, Weiss keeps them together with the hope that the three-batter minimum will force that lefty reliever to also face Riley and possibly the right-handed version of switch-hitter Ozzie Albies.

Knowing this, it’s safe to say everything went according to plan as the Braves secured a three-game series sweep with a 4-2 win over the Phillies on Sunday night at Citizens Bank Park. Albies highlighted the go-ahead three-run fifth inning with an RBI double off lefty reliever Tim Mayza.

Most everything has gone right for the Braves (15-7), who have won five straight to gain a five-game lead over the Marlins and Nationals in the National League East through just 22 games. No other current division leader has more than a half-game lead.

The Braves lead MLB in runs scored (122) and ERA (2.66). Weiss’ first three weeks as the team’s skipper have gone as well as anyone could have expected.

After Kyle Schwarber gave the Phillies a 2-0 lead with his first-inning homer off Grant Holmes, the Braves’ recent success provided reason to think the tide might turn during this series finale. It did, when the suddenly hot Michael Harris II and Ronald Acuña Jr. began the fifth with consecutive singles against Phillies starter Andrew Painter.

This prompted Philadelphia manager Rob Thomson to call Mayza out of the ‘pen to face Baldwin with two on and none out. Atlanta’s catcher walked and Olson followed with a grounder to Bryson Stott that proved too slow to turn into a double play. Riley followed with a dribbler to the left side that scored the go-ahead run. Albies followed with his double off the left-center-field wall.
