The San Francisco Firemen

When you think of the San Francisco Giants bullpen, you think of Brian Wilson. Since assuming the closer’s role four years ago, Wilson has been the face – and the beard – of relief pitching in the Bay Area. That recognition comes with merit since the right-hander has been one of the better relief pitchers in baseball and his save totals (160 since 2008) shows he is well-equipped with the closer’s mentality. While he has done a great job closing the door, the pitchers bridging the gap from starting pitcher to Wilson has been as good, if not better.

As a unit, Bruce Bochy’s bunch has been a top-3 bullpen this season. More specifically, he has deployed a lefty/righty combination of high-leverage relievers to lock down the innings prior to his closer. From the left side, Javier Lopez has been quite the pickup for the Giants since joining the club in late 2010. As an alumni of the FanGraphs’ school of higher leverage, Lopez has settled in as one of the more dependable lefties in relief.

Coming into Wednesday evening, Lopez had tossed 42 innings with a 2.57 ERA and a 3.16 FIP. His xFIP of 3.92 is much higher; however, he is an extreme groundball pitcher with GB rates above 60% in each of the last two seasons. Because of this, his home run rate is usually below the norm, meaning he is a perennial candidate to outperform his xFIP. Lopez has taken that theory to the max this year as the lefty has yet to allow a home run to any of the 174 batters he has faced.

The one flaw with Lopez comes in the form of splits. Not uncommon for his skill-set – a soft-tossing, left-handed reliever – right-handed batters have much more success against him their left-handed counterparts. Despite the difference in effectiveness (3.94 FIP vs. RHB, 2.45 FIP vs. LHB), Lopez has actually faced more RHB (92) than LHB (82). Considering some of the non-closing, right-handed pitchers available in the Giants’ bullpen, this is a rather unnecessary exercise.

One of those right-handers is Sergio Romo. Despite his small stature (listed at 5-foot-10 and 185 pounds) and his relative lack of “stuff” (average fastball velocity of 89.5 this season), Romo can rack up strikeouts with the best of them. Among qualified relievers, his 12.87 K/9 ranks sixth best in the major leagues. Where Romo sets himself apart from his fellow strikeout artists is command and control. Of the five names above him, only Vinnie Pestano of the Cleveland Indians has a BB/9 less than 3.00. Romo, on the other hand, has a BB/9 of 1.01. While striking out 52 batters this season, he has allowed just four walks and one of those was intentional.

Unlike his left-handed partner, Lopez, Romo has been deployed as a specialist by Bochy. Although he has shown the ability to get left-handed batters out (2.84 FIP/4.00 xFIP career), Romo has pitched with the platoon split to his advantage 72% of the time this season. That ties him for the highest rate among relievers with at least 30 innings pitched. Oddly enough, he is tied with teammate and fellow right-hander Ramon Ramirez, another sign that Lopez should not be facing as many right-handed batters.

Because he has been death to righties (0.44 FIP/0.84 xFIP) and his manager has put him in favorable situations most often, Romo has become a true relief ace. In fact, he leads the majors in both FIP (1.20) and xFIP (1.56) for relief pitchers. Since he is used so systematically, he has pitched just 35 innings despite 50 appearances; however, those 35 innings have been worth 1.6 WAR.

While Wilson will continue to rack up the saves – and therefore all the glory – it is the work of Lopez, Romo, and others – like Ramirez and Jeremy Affeldt – that afford him with the opportunity to shine in the ninth inning. Although they may never appear on the Rolaids Relief Man leaderboard (that would currently be…Brian Wilson), it is the unsung members of the San Francisco pen who are putting out the early inning fires before Wilson is able to cross his arms and signify another Giants’ victory.

Romo faced 29 batters in July and allowed ONE baserunner. Good enough for a 0.10 WHIP. He backed that up with a tidy 12.1 K/9. Just not fair.

Yeah, Bochy using Lopez against so many RHB is infuriating. Dude usually runs a tight bullpen so it’s especially mysterious.

It’s like he thinks Romo is the ROOGY when it’s clearly the other way around. I have no idea what he sees that makes him think otherwise, especially since he has the biggest hard on for lefty/righty matchups when it comes to assembling lineups/PH appearances.

crzy

I think the reason that Bochy won’t use Romo against right handers is because he still can’t forgive him for those two runs he gave up against the Braves in the NLDS, costing them the game.

When the Giants bullpen has been so good and is likely the biggest reason they are in first place, and even why they won the championship last year, I just don’t understand how you can call Bochy’s management “infuriating.” Infuriating for the opposing teams, maybe, but certainly not for me. Personally I love the way Bochy manages the bullpen.

As for Lopez facing RH batters, it’s often because of switch-hitters that Bochy would rather have batting RH, or else a RH batter sandwiched between 2 LH batters.

Bochy’s management is just fine, thank you!

The Giants wouldn’t have gotten where they are without either one and if you want to say the SP’s are more important, that’s OK with me. Doesn’t make change the main point of my comment which is I’m more than happy with Bochy’s management of the bullpen. Come to think of it, I’m fine with his management of he starters too!

A comment saying Bochy’s bullpen management is “infuriating” is about as ignorant as someone who claims to be a knowledgeable baseball fan can get.

The reason Bochy doesn’t use him more against LHB is his slider is not as effective, his cut FB hasn’t been dramatically effective from a low 3/4 realease and tends drift over the plate at 90 MPH, a batting T.

What do you mean? are you saying that a sidewinding lefty’s slider is going to be more effective against right handers? A sidewinding lefty who, unsurprisingly, has demonstrated a very large career and seasonal platoon split?

DrBGiantsfan

Lopez’ slider breaks in two planes and induces a lot of ground balls. He can throw it at the back foot of a RH batter for a K.

Romo’s slider is a 1 planer. It has more sideways break than any other slider in baseball and is unhittable for RH batters but he can’t break to down at the back foot to LH batters. If he throws the slider to break off the plate inside, it hits the batter. If he goes back door with it, it breaks right into the LH batter’s wheelhouse.

Romo is starting to occasionaly throw a nice little fading changeup to LH batters but until it’s more developed and he has more confidence in it, I can certainly see why Bochy doesn’t trust him against LH batters.

DD

I’ve heard Romo’s slider is a “no-dot” slider, meaning because of his relase point a red dot from the spinning seams does not show to the hitter, and they can’t recognize it. I’d expect this to be more true for RHB.

ElJimador

Career Platoon Splits:

Lopez:
vs. RHB: .291/.377/.420 (.797 ops)
vs. LHB: .222/.315/.311 (.626 ops)

Ramirez:
vs. RHB: .199/.280/.314 (.594 ops)
vs. LHB: .257/.334/.397 (.731 ops)

Romo:
vs. RHB: .182/.235/.305 (.540 ops)
vs. LHB: .195/.259/.295 (.554 ops)

I can understand looking at Romo’s stuff and thinking he shouldn’t be as effective vs. lefties. But shouldn’t actual results matter at some point?

Matt

Indeed it is a “no dot” slider. I’d be interested in all the pitchers in the league with a no dot slider…all I know for now is Romo and Gregorson.

DrBGiantsfan

This year:

Lopez .253 vs RHB; .137 vs LHB.

Romo .257 vs LHB; .111 vs RHB.

Romo has allowed 2 HR’s 1 vs RHB and LHB each. Lopez has allowed 0 HR’s.

Again, a lot of the RHB’s Lopez faces are switch hitters who I’m guessing don’t have as good numbers from the right side so that’s the way Bochy wants them to bat. He also faces some RHB’s who are sandwiched between two LHB’s. Then there’s always pinch-hitters with opposing managers trying to get a better matchup.

The Giants have 2 LHP’s in the bullpen whereas they have 5 RHP’s so it wouldn’t be surprising that Bochy would want to keep Lopez in for for a RHB sandwiched between two LHB’s so he doesn’t have to burn up 2 lefties in one inning.

I have no problem with a minor disagreement with Bochy’s bullpen strategy, but the one thing the man has always had in his entire managing career is great bullpens. To call his bullpen management “infuriating” is just plain ignorant!

ElJimador
14 years ago

DrB you keep saying that the righties Lopez faces are either sandwiched between 2 lefties or are switch hitters who we should want hitting from the right side, but look at the numbers. Lopez has actually faced more RHB this year than LHB (94 to 83). Not only that, he’s even faced more RHB than Romo has (93 vs only 36 LHB)! So in terms of usage clearly it’s not just the occasional “sandwiched” righty or Lance Berkman that Lopez is facing. It’s more like Romo doesn’t get the call at all unless he’s coming in to face back to back RHB. As in,

RRL = Romo, but
LRL = Lopez
LRS = Lopez
SRL = Lopez
RLR = Lopez

etc. Otherwise you can’t get to those usage numbers. As for effectiveness, you point to BA and HR splits how about the fact that RHB have an OBP nearly 100 points higher vs. Lopez (.376) than LHB have vs. Romo (.278)?

I don’t question Bochy’s managing on a lot but the way he uses Lopez and Romo is entirely backwards, especially when it comes to the 8th inning hold situations. It should be Lopez used as the specialist while Romo is the guy left in to face the opposite handed or switch hitters sandwiched in between.

Don’t worry it’s a known fact that neither Sabes or Bochy have Internet access, and even if they did they have no use for you nerbs and your crazy statz. FACT: Javier Lopez has 5 wins, Sergio Romo only has 3.

AustinRHL

Lopez is somewhat unusual in being a ground-ball pitcher with a depressed HR/FB for his career. Generally, high-GB% guys have inflated HR/FB, although of course their HR/9 will still be low. Roy Halladay, Derek Lowe, Brandon Webb, and Brandon League are good examples of the phenomenon.

Jim
14 years ago

With regard to Lopez, the ‘extreme groundball pitcher’ element shouldn’t help his xFIP, right? xFIP normalizes HR/FB, not HR/9 or anything. His xFIP should still be based on the assumption that, given a fly-ball, whats the percentage it is a home-run? The fact that he gives up less fly balls has no bearing on this.

In fact, the glossary indicates that “…groundball pitchers typically have a higher HR/FB rate than flyball pitchers.” Perhaps meaning that when a groundball pitcher misses, it’s with the kind of pitch that gets walloped. So shouldn’t he be a candidate to underperform his xFIP?

I should’ve made it more clear. Because GB & a low HR/9 his FIP is generally lower that his xFIP which has bounced around because of HR/FB fluctuation.

That still doesn’t make sense, Tommy. There’s no reason (other than luck) that a groundballer should have an FIP lower than his xFIP.

Looks to me that Lopez has simply gotten lucky on flyballs for his career, and you’re groping to find an explanation for it.

Not really. As you’ve pointed out, he’s an extreme groundballer and a LOOGY. That means that you’re dealing with a very small sample size of flyballs each season. Hence, less of an opportunity for the numbers to stabilize withithe season.

Matt

Reply to  Yirmiyahu

The extreme groundballer part of your statement is accurate, the LOOGY part, no so much. For his career he has faced 739 lefties and 743 righties, more right handed hitters than left handed. He should be a LOOGY, but he’s never really been used as one.

Being a Giants fan with a fine, dark beard who watches Sergio Romo pitch on a regular basis I bristled a bit at the “lack of stuff” line. No, he doesnt throw 98, but are radar gun readings the definition of ‘stuff’? Romo’s slider breaks bigger than Hawaii’s North Shore. That qualifies as ‘stuff’ to me. Dude is filthy.

The “no dot” slider Romo throws is due to the way he releases it. He throws it so the dot is behind the ball instead of out front, so the hitter cant pick it up until its too late.
