Starting Pitchers for Arizona and Pittsburgh

Merrill Kelly will take the mound for Arizona against Pittsburgh right-hander Bubba Chandler. Kelly enters with an 8-8 record, a 5.12 ERA and a 1.48 WHIP through 103.2 innings. He has allowed 112 hits and 22 home runs while recording 65 strikeouts and issuing 41 walks. Chandler is 3-8 with a 4.47 ERA and a 1.39 WHIP over 100.2 innings. He has surrendered 84 hits and 10 home runs while collecting 90 strikeouts and walking 56 batters. Kelly has five more victories and 15 fewer walks, but Chandler owns the better ERA, WHIP, hit total, strikeout total and home-run prevention numbers.

Arizona Arrives With Considerable Recent Momentum

Arizona carries a 55-50 overall record into this road matchup, although its 24-28 record away from home places it four games below .500 in that setting. The Diamondbacks recently lost 5-3 at Washington, but that defeat followed four consecutive victories. They recently won 3-2 over Washington, 10-6 over St. Louis, 15-5 over the Athletics and 6-5 in 10 innings over the Athletics. Arizona has therefore captured four of its last five games.

The Diamondbacks are batting .242 with a .313 on-base percentage and a .393 slugging percentage. They have accumulated 845 hits, scored 472 runs and hit 101 home runs. Arizona’s pitching staff owns a 4.22 ERA and a 1.29 WHIP while allowing opponents to hit .252. The staff has issued 307 walks and recorded 710 strikeouts. Arizona is also 22-19 in day games.

Arizona’s strongest current argument is its combination of an above-.500 overall record and four victories across the five most recently provided results. The Diamondbacks have scored at least six runs in three of those games, including performances of 10 and 15 runs. Their concern in this matchup is a starting-pitching comparison that favors Pittsburgh in several categories. Arizona’s scheduled starter owns a 5.12 ERA and has allowed 22 home runs, while the opposing starter has a 4.47 ERA and has surrendered 10.

Pittsburgh Looks to Reignite Its Productive Offense

Pittsburgh enters Monday at 53-52 overall and 27-26 at PNC Park. The Pirates have struggled across their five most recently provided results, losing 11-0 and 3-2 in 10 innings against the Chicago Cubs. They also recently lost twice to the New York Yankees by scores of 2-0 and 8-5, with their only victory during the stretch coming by a 5-3 score in 10 innings. Pittsburgh is consequently 1-4 over its last five games.

The Pirates are hitting .259 with a .337 on-base percentage and a .420 slugging percentage. Pittsburgh has collected 946 hits, scored 545 runs and produced 132 home runs. Its pitching staff carries a 4.30 ERA and a 1.31 WHIP while limiting opponents to a .240 batting average. The Pirates have issued 377 walks and recorded 970 strikeouts. Pittsburgh’s 29-18 day-game record is the better of the two teams.

Pittsburgh’s primary strength is an offense that leads Arizona in every supplied team batting category. The Pirates hold advantages of 17 points in batting average, 24 points in on-base percentage and 27 points in slugging percentage. They have also produced 101 more hits, 73 more runs and 31 more home runs. The weakness is the club’s recent 1-4 record, which includes two shutout losses and only 10 total runs across the five supplied results.

Arizona Diamondbacks vs Pittsburgh Pirates Picks and Prediction

Arizona Diamondbacks vs Pittsburgh Pirates Pick

• Pick: Pittsburgh Pirates Moneyline

Pittsburgh has lost four of its last five, while Arizona has won four of five, but the broader matchup numbers point me toward the Pirates. Pittsburgh owns the stronger batting average, on-base percentage and slugging percentage while leading Arizona by 73 runs and 31 home runs. The Pirates also have the better starting-pitcher ERA and WHIP, and ESPN Analytics gives Pittsburgh a substantial 62.4% winning probability. Arizona’s recent form makes this a competitive matchup, but Pittsburgh’s offensive advantages and 27-26 home record support the moneyline pick.

Arizona Diamondbacks vs Pittsburgh Pirates Total Pick

• Pick: Over 8.5

Take the over if the total is set at 8.5. I would play the over because Pittsburgh has scored 545 runs with a .420 slugging percentage and 132 home runs, while Arizona has scored 472 runs with a .393 slugging percentage. The scheduled starters carry ERAs of 5.12 and 4.47, and Arizona’s starter has allowed 22 home runs. Arizona has also scored six or more runs in three of its last five games. Those figures give this matchup enough offensive potential to reach at least nine combined runs.

Final Score Prediction: Pittsburgh Pirates 6 – Arizona Diamondbacks 4
