Answer by taking a quote from the following article:

The Outfield were an English rock band based in London, England. The band achieved success in the mid-1980s and are best remembered for their hit single, "Your Love". The band's lineup consisted of guitarist John Spinks, vocalist and bassist Tony Lewis, and drummer Alan Jackman. They had an unusual experience for a British band in that they enjoyed commercial success in the US, but never in their homeland.

Bassist/singer Tony Lewis, guitarist/keyboardist and songwriter John Spinks and drummer Alan Jackman played together in the late 1970s in a straightforward power pop band called Sirius B. After rehearsing for about six months and playing several gigs, their style did not match the punk rock that was surging in popularity in England and they broke up. Several years afterward, the three gathered back together in London's East End under the name The Baseball Boys. They performed in and around England until a demo got them signed to Columbia/CBS Records in 1984.  Spinks adopted the name 'Baseball Boys' from a teen gang called "The Baseball Furies" in the cult film The Warriors, a movie that he had just seen. Although he used the name as a joke and "just to be outrageous", record company people responded favourably. The band got a reputation as a very "American-sounding" group and signed in the US after playing for just a few months in England. Their manager, an American living in England, recommended a new band name with a similar attitude since 'Baseball Boys' seemed too "tacky" and "tongue-in-cheek". Spinks has said, "the Outfield was the most left-wing kind of thing we liked."  Spinks expressed an interest for the American sport of baseball, while also being a devoted fan of association football. He claimed that the group "didn't know what an outfield was" until they came to the US, and that "We're just learning about baseball. It's an acquired taste and we're trying to acquire a taste for it." He expounded upon this in a Chicago Tribune piece:  The thing about American sports - baseball and football - is that they're far more show business, far more a spectacle, than British sports. In England, it's just sort of everyday soccer matches. You get 30,000 people in the freezing cold in the middle of winter watching guys chase around in mud. In America, you have the sunny days, and the baseball diamond is really nicely laid out. In England, you'd see these guys covered in mud within 10 minutes. It's not such a nice spectacle to watch.  Their debut album, Play Deep, produced by William Wittman, was issued in 1985, and was a success. The album would go on to reach triple platinum sales status and the Top 10 in the US album charts; it also featured a Top 10 single entry with "Your Love", which peaked at No. 6. It went on to be featured in a number of 80s-themed compilation albums, and over 1,000 covers and remixes by other artists have been released physically and/or online. The band toured extensively, opening for Journey and Starship. Spinks made a point of mentioning in interviews that the band was "totally into not smoking or doing drugs".

What were their successes?
