Starting Pitchers

Pittsburgh will send Braxton Ashcraft to the mound against St. Louis left-hander Matthew Liberatore. Ashcraft enters with an impressive 13-5 record, 3.59 ERA and 1.07 WHIP through 155.1 innings. He has allowed 132 hits while recording 161 strikeouts against only 34 walks, although he has surrendered 21 home runs. Liberatore has had a much more difficult season, carrying a 5-12 record with a 5.44 ERA and 1.47 WHIP through 129 innings. He has surrendered 144 hits and 23 home runs while striking out 132 and walking 45. The starting pitching numbers provide Pittsburgh with a significant statistical advantage entering the series finale.

Pirates Have the Starting Pitching Edge

Pittsburgh comes into Sunday at 66-71 after snapping a two-game losing streak with Saturday's 6-2 victory. The Pirates have gone 3-2 over their last five games, with the other two victories coming against San Diego by scores of 1-0 and 3-2 in 12 innings. Their losses during that stretch were 3-0 against San Diego and 4-1 against St. Louis. Pittsburgh has therefore held its opponent to two runs or fewer in four of its last five games.

The Pirates have produced the stronger offensive numbers of these two teams over the full season. Pittsburgh is batting .252 with 658 runs, 1,178 hits and 158 home runs while posting a .329 on-base percentage and .403 slugging percentage. St. Louis enters Sunday with a .241 average, 604 runs, 1,103 hits and 142 home runs, so Pittsburgh owns the statistical advantage in each of those categories.

Pitching has been nearly even at the team level, with Pittsburgh carrying a 4.21 ERA and 1.31 WHIP compared with St. Louis at 4.22 and 1.34. The Pirates have also held opposing batters to a .238 average, considerably better than the Cardinals' .253 mark. When that season-long pitching profile is combined with Pittsburgh's advantage in Sunday's starting matchup, there is a strong case for backing the visitors.

Cardinals Look to Win the Series at Home

St. Louis is 68-69 overall and sits two games ahead of Pittsburgh in the NL Central standings, but the Cardinals have struggled to establish much of a home-field advantage this season. They are 34-37 at Busch Stadium and enter the finale having dropped three of their last five games.

The Cardinals have experienced some wild swings offensively during that five-game stretch. They scored 13 runs in a loss against Baltimore, followed by seven in another loss, before scoring seven in a victory. Against Pittsburgh, however, St. Louis has managed just six runs through the first two games of this series. The Cardinals won the opener 4-1 but were held to two runs in Saturday's loss.

For the season, St. Louis is batting .241 with a .316 on-base percentage and .383 slugging percentage. The Cardinals have scored 604 runs with 142 home runs. Their 4.22 ERA is almost identical to Pittsburgh's 4.21 mark, but the 1.34 WHIP and .253 opponent batting average both trail the Pirates' numbers. With Pittsburgh also holding the more favorable starting pitching matchup Sunday, St. Louis will need to overcome several statistical disadvantages to secure the series.

Pittsburgh Pirates vs St. Louis Cardinals Picks and Prediction

Pick: Pittsburgh Pirates ML (-118)

Pittsburgh is the preferred side in Sunday's series finale. The Pirates have the better offensive numbers across batting average, runs, hits, home runs, on-base percentage and slugging percentage, while their overall pitching numbers are at least slightly better as well. Most importantly, Pittsburgh owns a sizable advantage in the starting pitching matchup. The Pirates have also won three of their last five and held opponents to two runs or fewer four times during that stretch. Rather than laying -1.5 runs at +142, the -118 moneyline offers the better balance between price and probability.

Pick: Under 8 (-111)

The Under is the second selection. Pittsburgh's recent games have been extremely low scoring, producing combined totals of eight, five, three, one and five runs over its last five contests. Four of those five finished below Sunday's number of eight. The Pirates' recent run prevention has been particularly impressive, and Sunday's starting pitching advantage gives them another opportunity to control the game. St. Louis has scored only six runs through the first two games of this series, while Pittsburgh has allowed just seven runs across its last five games. With a push providing some protection if the teams combine for exactly eight, Under 8 is the play.

Final Picks: Pittsburgh Pirates ML (-118) and Under 8 (-111)
