PHILADELPHIA -- Forget unbeatable, Ranger Suárez is borderline untouchable right now.

The Phillies left-hander continued his undefeated run to begin the season with another dominant outing in the club's 5-2 win over the Rangers on Tuesday night at Citizens Bank Park. Su¨¢rez tossed seven innings of one-run ball to improve to 9-0 with a 1.36 ERA through 10 starts.

To put that in perspective, Su¨¢rez is the first pitcher to start 9-0 with a sub-1.50 ERA through 10 games since Hall of Famer Juan Marichal in 1966. The only other AL/NL pitchers to do so since earned runs became official in 1912 are Hall of Famer Walter Johnson and Cy Falkenberg -- both in 1913.

¡°It's kind of mind-boggling, you know?¡± Phillies manager Rob Thomson said. ¡°The historic run that he's been on, he's just been pitching great. Knock on wood, he keeps it going.¡±

Even putting aside Su¨¢rez¡¯s undefeated record, his 1.36 ERA is the third lowest in franchise history through 10 starts. Only Grover Alexander -- another Hall of Famer -- posted a lower mark through 10 outings, doing so in both 1916 (1.24) and 1915 (1.31).

Su¨¢rez¡¯s latest gem included tying a career high with 10 strikeouts against the reigning World Series champion Rangers. He allowed five hits and two walks.

Though Su¨¢rez is known for his unflappable demeanor, even he must be in awe of some of these names he¡¯s being mentioned alongside ¡­ right?

¡°No, I just try to go and do the best work that I can,¡± Su¨¢rez said via a team interpreter. ¡°Try to keep the game close so the team can try to go out and get a win. That's the most important thing.¡±

Su¨¢rez may not bask in the historical significance, but that doesn¡¯t mean his teammates -- and the opposition -- aren¡¯t taking notice.

"It's incredible,¡± said Bryce Harper, who went 2-for-3 with a double, a homer and a walk. ¡°He goes out there every fifth day and he does his job, man. He knows what it takes to win games. He knows how to pitch."

Added Rangers four-time World Series-champion manager Bruce Bochy: ¡°We have our hitters¡¯ meetings and we cover everything -- his pitches, what to look for in certain areas, things like that. I mean, you cover all that so they're prepared, but he's just one of the best left-handers in the game right now with the way he's throwing the ball.¡±

Not that Su¨¢rez has needed much run support this year, but Harper certainly did his part to protect Su¨¢rez¡¯s winning streak. With the game tied at 1-1 in the fourth, the two-time MVP doubled before scoring the go-ahead run on an Alec Bohm single. Harper then added what proved to be the game-winning run with a no-doubt homer to straightaway center -- one day after he also knocked a ¡°promposal¡± out of the park for a local high school student.

Su¨¢rez took a no-decision in his first start of the season against the Braves. He's since won nine consecutive starts. The last Phillies pitcher to win nine straight starts at any point in a season: Earl Moore in 1910.

¡°He's kind of old school in that he's not going to light up the radar gun,¡± Thomson said. ¡°But he's going to command the baseball, he's going to work fast, he's going to change speeds -- it's just really fun for me to watch.¡±

Now, toss in the fact that Su¨¢rez has allowed only seven earned runs over 61 innings in those nine outings and he finds himself in rare territory for any point in a season. The only other pitchers in AL/NL history to win nine straight games while giving up seven earned runs or fewer:

? Blake Snell (2018)
? Johan Santana (2004)
? Cal Eldred (1992)
? Gaylord Perry (1974)
? Steve Blass (1968)
? Bob Gibson (1968)
? Warren Spahn (1961)
? Hoyt Wilhelm (1959)

That list of eight pitchers includes four Hall of Famers (Perry, Gibson, Spahn and Wilhelm) and two other two-time Cy Young Award winners (Snell and Santana).

¡°I enjoy the results that we get, and I enjoy the wins we get as a team,¡± Su¨¢rez said. ¡°But the next day after that, I forget about everything, because I have to focus on my next start.¡±

With the Phils trailing by a run in Su¨¢rez¡¯s last outing, Harper told the dugout, ¡°Let's get him a 'W¡¯¡± -- and promptly helped key a decisive four-run rally.

On Tuesday, he again helped Su¨¢rez remain undefeated.

"As a team, we're thinking about that, right?¡± Harper said. ¡°Any given night, for a guy to be able to go out there and be 9-0, we want him to get to 10-0 and 11-0 and so forth."
