09/12 Lotte @ Kiwoom

Lotte starting pitcher: Rodriguez Kiwoom starting pitcher: Alcantara

9th-place Lotte (43.3%) visits 10th-place Kiwoom (35.4%) - a bottom-of-the-table matchup on paper, but the season series has been lopsided, with Lotte up 11-2 (.850). Both teams are on 2-game losing streaks, so momentum isn't much of a separator.

Both starters have interesting stretches going on tonight. Rodriguez has a 4.35 ERA over 138.2 innings this season, but he's actually the better pitcher on the road, which is exactly tonight's situation - 3.43 ERA / 3.53 FIP over 76 innings away, well ahead of his 5.46 ERA at home. His last-5-start FIP has spiked to 6.00, but that looks driven mainly by home runs - he's allowed 6 in his last 26.2 innings - since his BABIP (.312) and LOB% (75.8%) over that stretch are right in line with his season marks (.317 / 74.9%); at a 26.2-inning sample, a couple of extra home runs can swing FIP a lot on their own. Alcantara has a 3.78 ERA over 143 innings with only a small home/road gap (3.69 at home vs. 3.93 away), so tonight's home start isn't a major factor either way for him, and his last-5-start FIP has improved to 3.14, so he looks to be in good form.

Head-to-head history splits the two starters in opposite directions. Rodriguez is 2.05 ERA against Kiwoom across 4 starts (26.1 IP), and his FIP (4.17) over that span is close enough to his season number that this looks like a genuine edge. Alcantara, on the other hand, is 4.50 ERA against Lotte over 4 starts (26 IP) - ugly on the surface - but his FIP there is a much better 2.72, meaning the process was fine and the results (poor luck on balls in play, a 65.5% strand rate) just didn't cooperate. In other words, Lotte's dominant season series (11-2) may not be telling the truth about Alcantara's actual stuff against them.

Both lineups remain unconfirmed, so this reflects the most recent game. Lotte's hitters have had real success against Alcantara - Jeon Min-jae is 5-for-12 (.417) and Hwang Sung-bin 5-for-10 (.500) - while Kiwoom's Park Chan-hyeok is 0-for-7 against Rodriguez. At the team level, both offenses have cooled by a similar amount: Lotte's wOBA is down from .342 to .296 over the last 5 games, and Kiwoom's from .329 to .303, so this isn't a one-sided slump.

Neither bullpen has been good lately, but Lotte's has been worse - a 8.10 ERA over the last 10 games versus Kiwoom's 5.73. Lotte has also burned through more arms recently (13 IP across 10 pitchers), so Kiwoom may have a relative edge if this comes down to the bullpens.

In summary, the season series heavily favors Lotte, but Alcantara's ugly-looking numbers against them may be understating his actual stuff once you account for FIP, and Rodriguez happens to be pitching in his stronger road role tonight. Given how depleted Lotte's bullpen already is, the late innings look like the biggest swing factor in this bottom-of-the-table matchup.
